I'm trying to add a transparent black overlay to an image whenever the mouse is hovering over the image with only CSS. Is this possible? I tried this:
http://jsfiddle.net/Zf5am/565/
But I can't get the div to show up.
<div class="image">
<img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
<div class="overlay" />
</div>
.image {
position: relative;
border: 1px solid black;
width: 200px;
height: 200px;
}
.image img {
max-width: 100%;
max-height: 100%;
}
.overlay {
position: absolute;
top: 0;
left: 0;
display: none;
background-color: red;
z-index: 200;
}
.overlay:hover {
display: block;
}
I'd suggest using a pseudo element in place of the overlay element. Because pseudo elements can't be added on enclosed img elements, you would still need to wrap the img element though.
LIVE EXAMPLE HERE -- EXAMPLE WITH TEXT
<div class="image">
<img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>
As for the CSS, set optional dimensions on the .image element, and relatively position it. If you are aiming for a responsive image, just omit the dimensions and this will still work (example). It's just worth noting that the dimensions must be on the parent element as opposed to the img element itself, see.
.image {
position: relative;
width: 400px;
height: 400px;
}
Give the child img element a width of 100% of the parent and add vertical-align:top to fix the default baseline alignment issues.
.image img {
width: 100%;
vertical-align: top;
}
As for the pseudo element, set a content value and absolutely position it relative to the .image element. A width/height of 100% will ensure that this works with varying img dimensions. If you want to transition the element, set an opacity of 0 and add the transition properties/values.
.image:after {
content: '\A';
position: absolute;
width: 100%; height:100%;
top:0; left:0;
background:rgba(0,0,0,0.6);
opacity: 0;
transition: all 1s;
-webkit-transition: all 1s;
}
Use an opacity of 1 when hovering over the pseudo element in order to facilitate the transition:
.image:hover:after {
opacity: 1;
}
END RESULT HERE
If you want to add text on hover:
For the simplest approach, just add the text as the pseudo element's content value:
EXAMPLE HERE
.image:after {
content: 'Here is some text..';
color: #fff;
/* Other styling.. */
}
That should work in most instances; however, if you have more than one img element, you might not want the same text to appear on hover. You could therefore set the text in a data-* attribute and therefore have unique text for every img element.
EXAMPLE HERE
.image:after {
content: attr(data-content);
color: #fff;
}
With a content value of attr(data-content), the pseudo element adds the text from the .image element's data-content attribute:
<div data-content="Text added on hover" class="image">
<img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>
You can add some styling and do something like this:
EXAMPLE HERE
In the above example, the :after pseudo element serves as the black overlay, while the :before pseudo element is the caption/text. Since the elements are independent of each other, you can use separate styling for more optimal positioning.
.image:after, .image:before {
position: absolute;
opacity: 0;
transition: all 0.5s;
-webkit-transition: all 0.5s;
}
.image:after {
content: '\A';
width: 100%; height:100%;
top: 0; left:0;
background:rgba(0,0,0,0.6);
}
.image:before {
content: attr(data-content);
width: 100%;
color: #fff;
z-index: 1;
bottom: 0;
padding: 4px 10px;
text-align: center;
background: #f00;
box-sizing: border-box;
-moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
opacity: 1;
}
CSS3 filter
Although this feature is only implemented in webkit, and it doesn't have browser compatibility, but It's worth taking a look at:
.image img {
max-width: 100%;
max-height: 100%;
-webkit-transition: .2s all;
}
.image img:hover {
-webkit-filter: brightness(50%);
}

You were close. This will work:
.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }
You needed to put the :hover on image, and make the .overlay cover the whole image by adding right:0; and bottom:0.
jsfiddle: http://jsfiddle.net/Zf5am/569/
Here's a good way using :after on the image div, instead of the extra overlay div: http://jsfiddle.net/Zf5am/576/
<div class="image">
<img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
</div>
.image {position:relative; border:1px solid black; width:200px; height:200px;}
.image img {max-width:100%; max-height:100%;}
.image:hover:after {content:""; position:absolute; top:0; left:0; bottom:0; right:0; background-color: rgba(0,0,0,0.3);}
.overlay didn't have a height or width and no content, and you can't hover over display:none.
I instead gave the div the same size and position as .image and changes RGBA value on hover.
http://jsfiddle.net/Zf5am/566/
.image { position: absolute; border: 1px solid black; width: 200px; height: 200px; z-index:1;}
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; background:rgba(255,0,0,0); z-index: 200; width:200px; height:200px; }
.overlay:hover { background:rgba(255,0,0,.7); }
See what I've done here: http://jsfiddle.net/dyarbrough93/c8wEC/
First off, you never set the dimensions of the overlay, meaning it wasn't showing up in the first place. Secondly, I recommend just changing the z-index of the overlay when you hover over the image. Change the opacity / color of the overlay to suit your needs.
.image { position: relative; width: 200px; height: 200px;}
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; background-color: gray; z-index: -10; width: 200px; height: 200px; opacity: 0.5}
.image:hover .overlay { z-index: 10}
You can accomplish this by playing with the opacity of the image and setting the background color of the image to black. By making the image transparent, it will appear darker.
<div class="image">
<img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
</div>
CSS:
.image { position: relative; border: 1px solid black; width: 200px; height: 200px; background: black; }
.image img { max-width: 100%; max-height: 100%; }
.image img:hover { opacity: .5 }
You might need to set the browser-specific opacity too to make this work in other browsers too.
I would give a min-height and min-width to your overlay div of the size of the image, and change the background color on hover
.overlay { position: absolute; top: 0; left: 0; z-index: 200; min-height:200px; min-width:200px; background-color: none;}
.overlay:hover { background-color: red;}

I have made a footer in Photoshop looking like this:
As you can see, the footer here is slightly arced all the way across. I have tried doing something with border-radius, but that almost only targets the edge, which makes the arc more curved in the edges, and not even receiving the effect of a subtle arced footer as seen in the image.
Is there an easy CSS way to do this, or do I need some JavaScript or something to achieve this?
Use a pseudo element of the footer with border-radius to make the arch.
I made them different colors here so you can see which element is which.
body {
margin: 0;
max-height: 100vh;
overflow: hidden;
}
footer {
bottom: 0; left: 0; right: 0;
position: absolute;
background: brown;
height: 10vh;
}
footer::before {
content: '';
background: red;
width: 200%;
position: absolute;
left: 50%;
top: -100%;
transform: translateX(-50%);
height: 1000%;
border-radius: 50%;
z-index: -1;
}
<footer></footer>
This solution uses a large width to get a more pleasant curve, but without the pseudo-element:
footer {
background-color: red;
width: 200%;
transform: translateX(-25%);
height: 200px;
border-radius: 50% 50% 0 0;
}
<div>
<footer></footer>
</div>
Its not perfect, but here i've got a really really big circle that's absolutely positioned with the overflow hidden so that you only see the top part of the arc.
#container{
background: grey;
height:300px;
width:500px;
position:relative;
overflow:hidden;
}
#arc{
position: absolute;
top:200px;
left:-800px;
width:2000px;
height:2000px;
border-radius:2000px;
background:brown;
}
<div id="container">
<div id="arc">
</div>
</div>
https://jsfiddle.net/z9pq1026/
You can actually use border-radius to do this without a pseudo element.
.arc {
width: 100%;
height:500px;
background: #000000;
border-radius: 50% / 30px;
border-bottom-right-radius: 0;
border-bottom-left-radius: 0;
}
<div class="arc"></div>
will work just fine. Make sure that when you use:
border-radius: 50% / 30px;
the first property is always "50%" as this will ensure the arc meets in the middle. The second property (after the "/") is the height of the arc measured from the middle to the edges
The circle solution, but it's responsive!
footer {
background: #ececec;
height: 200px;
width: 100%;
position: relative;
overflow: hidden;
}
.arc {
position: absolute;
top: 0px;
right: calc(-80%);
width: 300%;
padding-top: 100%;
border-radius: 100%;
background: black;
}
<footer>
<div class="arc">
</div>
</footer>
I have two divs that I am trying to stack over each other but the one I want on top is not showing. I want the blue background div to lay on top of the red background div. Any advice? The reason why I want to overlay the blue div is because the container is a centered grid and I want the red div to be the background for the first half of the page.
JSFIDDLE
CSS
.buddy {
width: 50%;
height: 629px;
display: inline-block;
position: relative;
background: red;
}
.buddy-content {
position: absolute;
top: -629px;
z-index: 10;
background: blue;
}
.container {
max-width: 1000px;
margin: 0 auto;
overflow:hidden;
position:relative;
padding: 0 10px;}
You have made the second div absolute so you don't need to give the negative value for top. The second div is hiding because you top -629px; Try making the top:0 and see. And also for your current code. Remove the overflow hidden and put z-index like this:
.buddy {
width: 50%;
height: 629px;
display: inline-block;
position: relative;
z-index:9;
background: red;
}
.buddy-content {
position: absolute;
top: -629px;
z-index: 10;
background: blue;
}
.container {
max-width: 1000px;
margin: 0 auto;
width:200px;
height:200px;
position:relative;
padding: 0 10px;
}
.buddy {
width: 50%;
height: 629px;
display: inline-block;
position: absolute;
background: red;
}
.buddy-content {
position: absolute;
z-index: 10;
background: blue;
}
<div class="buddy BlueGradient">
</div>
<div class="container">
<div class="buddy-content">
ROGER
</div>
</div>
https://jsfiddle.net/kt77cp3e/6/
just add z-index : higher to the div that you want to show on top and set z-index low to the other one ..
ant one thing your code is working good just you need to remove " top : -629px;"
that thing is not allowing blue div to be on top just it is showing at the -629 px position..!!!!
If you can update your code like this, it may solve the issue:
Demo:https://jsfiddle.net/kt77cp3e/7/
CSS:
html, body {
height:100%;
width:100%:
}
.container {
width:50%;
height:100%;
background:red;
position:relative;
}
.container>div {
position:relative;
left:0;
right:0;
}
.container>div:first-child {
top:0;
height:50%;
background:blue
}
.container>div:last-child {
bottom:0;
height:50%;
background:green
}
HTML:
<div class="container">
<div></div>
<div></div>
</div>
Update: Considering the latest updated code, I think you should remove overflow:hidden from the container styles. That should do the trick
You should set the dimension on the .container div.
CSS:
.container {
position:relative;
width:100px; //You may modify these values
height:100px
}
Demo: https://jsfiddle.net/kt77cp3e/1/
.buddy { width: 50%; height: 629px; display: inline-block; position: relative; background: red;}
.buddy-content { position: absolute; top: 0px; z-index: 10; background: blue; }
.container {max-width: 1000px; margin: 0 auto; overflow:hidden; position:relative; padding: 0 10px; position: relative;}
<div class="container">
<div class="buddy BlueGradient">
<div class="buddy-content">ROGER</div>
</div>
</div>
This brings the text "Roger" with blue background on top of the red background
I have the css transition working when the user hovers over item however when the mouse exits the div, content is pushed below during the transition. Below is my html/css along with a jsfiddle to show what I mean.
html:
<div id="container">
<div class="item">
<div class="img">
</div>
<div class="heading">
</div>
</div>
</div>
css:
#container {
width: 100%;
height: 100%;
}
.item {
width: 100%;
height: 400px;
position: relative;
}
.img {
background: #000;
width: 40%;
height: 400px;
float: left;
transition: width 0.5s ease;
}
.heading {
width: 60%;
height: 400px;
float: right;
background: #900;
transition: width 0.5s ease;
}
.item:hover .img {
width: 100%;
}
.item:hover .heading {
width: 100%;
background:rgba(255,255,255, 0.9);
position: absolute;
top:0;
left:0;
}
JSFiddle
I am sure it is a simple position problem. However, I am not familiar enough with the transition to know where to find the answer.
Updated position to
tranform: translateY(-100%);
in order to get rid of the non-transition property. Now before/after :hover the div heading gets pushed below item. Updated JSFiddle to show.
Updated transition: all to transition: width on both img and heading which fixed heading getting pushed below img on :hover, however the original problem of heading being pushed below when user exits :hover is still an issue.
I think I found the answer:
by making heading have position:absolute;, I can have it forced to stay inside of the item div, keeping it from moving below it. So my updated css (with actual class names and production stuff) looks like;
.flight {
height: 400px;
position: relative;
}
.flight-img {
background: red;
background-size: cover;
width: 40%;
height: 400px;
float: left;
position: relative;
/* CSS Animation Effects */
transition: width 0.5s ease;
}
.flight-heading {
width: 60%;
float: left;
position: absolute;
top: 50%;
right: 0;
transform: translateY(-50%);
transition: width 0.5s ease;
}
/* Alternate img float ***
/* Probably an easier way but this works for now */
.flight:nth-of-type(4n-1) .flight-img{
float: right;
}
.flight:nth-of-type(4n-3) .flight-img{
float: left;
}
.flight:nth-of-type(4n-1) .flight-heading{
left:0;
}
.flight:nth-of-type(4n-3) .flight-heading{
float: right;
}
/* Adding hover effects for desktop */
.flight:hover .flight-img {
width: 100%;
}
.flight:hover .flight-heading {
width: 100%;
position:absolute;
top:0;
left:0;
transform: translateY(50%);
background: rgba(0,0,0,0.75);
color: #fff;
h2 {
color: #fff;
}
}
while my html looks like:
<div id="flights">
<div class="flight">
<div class="flight-img"></div>
<div class="flight-heading">
<h2>Shared Flights</h2>
<p>The shared flight option is available for 1 to 5 people. This is our most economical flight. You will fly with other passengers that are booked that day.</p>
<button>Book Now</button>
</div>
</div>
<div class="clear"></div>
</div><!-- End Flights -->
with a JSFiddle to show. I know the animation needs work, but I figure making it smooth will be easy now that the divs stay in one place.

Your question also contains the answer.
I want the div .top & .header equal to the width of the body
This could be achieved by having an attribute / property of width: 100%;
but it limits to the width of the container
This is because the container is the parent of the child element. Which means the max width of the child element is the width of the parent.
I want it remain inside the container class.
Which means, you'll have to give the container the property of width: 100%.
You can also solve this by using the overflow property, but I assume that is not what you'd like.
http://www.w3schools.com/cssref/pr_pos_overflow.asp
Which ofcourse means:
.container {
position: relative;
width: 100%;
height: 800px;
border: 1px solid #fff;
background: url(images/bg_home.jpg) no-repeat right;
margin: 0 auto;
z-index: 0;
}
Also, not related to your question but to your CSS, you have a property of background which loads an image and not repeat.
Is this what you want or is it a pattern? In the last case, consider it making a small picture to repeat over the entire page, this reduces the load time of the webpage.
If the question was regarding your background not meeting the bodys width, consider adding it to the body tag instead of the container tag.
Although you have given .top and .header a width of 100% - they sit inside the container div which has a width of 910px. Therefore by saying .top width 100% you are basically saying .top width 910px because it is a child of container therefore it will take on those styles.
Why do the .top and .header need to sit inside the container? If you would them to be 100% i.e. fill the whole browser window, then you should take them outside the container div.
Good luck
Like this
please remove width:100%; for below selector:
css
.top {
background: #00112b;
position: relative;
height: 49px;
z-index: 2;
opacity: 0.50;
filter: alpha(opacity=50);
}
.header {
position: relative;
left: 0;
opacity: 0.50;
filter: alpha(opacity=50);
background: #012e46;
height: 99px;
z-index: 2;
}
http://jsfiddle.net/cxwQF/12/.
Note: Red and green boxes should intersect. Green box is image or video. When hover it became yellow. But not on the bottom where the red box starts. Red box is control (for example, next image).
Question. How can I put parent div behind the image and child div to the top.
Markup:
<div id='image'></div>
<div id='parent'>
<div id='child'></div>
</div>
CSS:
#image {
position: relative;
width: 100%;
height: 500px;
background: green;
z-index: 2;
}
#image:hover {
background: yellow;
}
#parent {
position: fixed;
bottom: 0;
width: 100%;
z-index: 1;
}
/*#parent:hover {
background: blue;
} */
#child {
position: relative;
margin: 0 auto;
width: 100px;
height: 100px;
background: red;
z-index: 3;
}
How does this suit you? It's hard to know how to structure it without knowing what you are trying to achieve.
http://jsfiddle.net/cxwQF/21/
I've created another, invisible div for your 'child' but the original (foot) remains in the same place.
<div id='image'></div>
<div id='foot'>
</div>
<div id='parent'>
<div id='child'></div>
</div>
Sorry about the border styles its purely for test purposes.
I found the pure CSS solution. Markup remains the same.
CSS:
#image {
width: 100%;
height: 500px;
background: green;
}
#image:hover {
background: yellow;
}
#parent {
position: fixed;
bottom: 0;
width: 100%;
z-index: 1;
visibility: hidden;
}
#child:hover {
background: pink;
}
#child {
margin: 0 auto;
visibility: visible;
width: 100px;
height: 100px;
background: red;
}
Solution: #parent's "visibility" should be set to "hidden", #child's "visibility" should be set to "visible"
